The short answer
Basin Gulch lies in the historic Philipsburg Mining District of west-central Montana, about one hour from Butte. Lannister Mining reports that the property is primarily on patented land, hosted in oxides, and open at depth, along strike and untested regionally, with about two-thirds of the ground still unexplored.
Figures as published by Lannister Mining, as of November 2026.
Land tenure
The property is underlain by a core of patented mining claims surrounded by unpatented mining claims. In total, Lannister Mining holds 11 patented claims and 53 unpatented claims covering 1,107 hectares, and reports multiple high priority targets near the historic resource.
A patented claim is one where the US federal government has transferred title, so it is held as private land. An unpatented claim gives the holder the right to explore and develop minerals on federal land without owning the surface. A patented core is a meaningful detail for anyone assessing tenure risk.
Geology
Lannister Mining describes high grade gold-silver mineralization near surface, which it says implies significant flexibility in future mine design optimization. Mineralization is hosted in oxides. In general, oxide-hosted gold has been weathered near surface and can be simpler to process than gold locked in sulfide minerals.
The company reports that mineralization is open in multiple directions and at depth. It also states that the property has not been mined out, so the historical mineralization remains in place for evaluation. Drill and trench highlights are listed on the Basin Gulch technical summary.
Open at depth, along strike and untested regionally.
Access
Yes. Basin Gulch has year-round access from Philipsburg, Montana, on paved and well-maintained gravel roads, and is only about one hour from Butte. For a field program, that means crews, drill rigs and samples can move without seasonal shutdowns caused by access.
With about two-thirds of the Basin Gulch Property still unexplored, Lannister Mining sees substantial room for new discovery beyond the historic resource area. Future drilling will concentrate on additional mineralized target areas within the property.
The company says the property has potential to host a significant Maiden Mineral Resource Estimate after expansion and confirmation drilling of historical drill intercepts. That estimate has not yet been published. See why it matters to investors.
